Now I don't have a netbsd-box to test this on, but from looking at the
code it seems like that the following patch might help.  You need to
run `autoreconf -f' and then re-run configur after having applied this
patch.  If you get any warnings while compiling the xfs module at all
please send them to me as they could indicate that something is wrong.
